Correct.  Perhaps "Use %PRIu32 and such to print integers of fixed length"?

The only worry I have with this patch is with systems with not-so-ANSI
headers; as you noticed, we already have:

        #ifndef PRIuMAX
        #define PRIuMAX "llu"
        #endif

in git-compat-util.h, which does include <inttypes.h>, so PRIu32 and
friends could be problematic on these platforms.

Hmm.  Is this change necessary?
